Now, King Okkāka had a slavegirl named Disā. She gave birth to a boy named Black. When he was born, Black Boy said: ‘Wash me, mum, bathe me! Get this filth off of me! I will be useful for you!’ Whereas these days when people see goblins they recognize them as goblins, in those days they recognized goblins as ‘blackboys’. They said: ‘He spoke as soon as he was born—a blackboy is born! A goblin is born!’ From that day on the Kaṇhāyanas were proclaimed, and he was their founder. That’s how, recollecting the ancient name and clan of your mother and father, the Sakyans were the children of the masters, while you’re descended from the son of a slavegirl of the Sakyans.”

When he said this, those young students said to him, “Worthy Gotama, please don’t put Ambaṭṭha down too much by calling him the son of a slavegirl. He’s well-born, a gentleman, learned, who enunciates well, and is astute. He is capable of debating with the worthy Gotama about this.”
